Application filed October a, 1914. serial 110. 894,607.

To all whom may concern Be it known that I, JoHN citizen of the United States, residing at Ipswich, county of Essex, State of Massachusetts, have invented a certain new and use ful Improvement in Heel-Breasting Machines, of which the followingis a specihad therein to the d. SULLrvAN, a

accompanying drawings. v

The hereinafter described invention isan improvement on the heel breast ng machine application filed shown and described in m a May 27, 1914, Serial No. 81,364, and relates particularly tothe type of machine shown.

in Figure 5 of said application but not spe cifically claimed therein, in which a single trimming knife is employed, the heel being supported against a suitably shaped cutting block, the face of which is movable to pre sent diilerent portions thereof to the edge of the knife.

combine with a heel breasting machine'of this type means for simultaneously breasting the top lift of the heel, the upper edge of which cannot be satisfactorily breasted.

by a knife or knives moving inwardly" from the sides toward. the center of the heel; also to breast the top lift and intermediate lifts concavely to give to the heel amore attractive appearance. I accomplish these ob ects by providing a vertically moving knife which automatically breasts the inner side of the top lift after the horizontally moving knife has formed the front of the .heel. As the pressure produced by the vertically moving breasting knife is exerted directly against the operator who holds the chosen its jack in operative position, I have provided means for positively supporting the jack while the cutting is taking place. The machine also contains certain other' impon tant improvements which will be hereinafter fully described.

In the drawings, Fig. 1 is a front elea machine embodying" my inven-. tion. Fig. 2 is a. section on line 2-2 of Fig. 1, looking in the direction of the arrows.

heel rest. Fig. 8 is a view in perspective of the-breast of a heel showing the cuts produced bythe two breasting knives.

Referring to the drawings, and particularly to Fig. 8 at A is shown'a heel whichhasbeen breasted by. the machine embodying my present invention. 'Thexhorizontal cut designated by a is made by 'a concave horizontal .breasting' knife, the shoe being sup ported against a cuttingblock which .will be described later. The vertical c'utis desi nated b and is made by a vertical 2' kniie called for convenience thetop breasting knife. It will be seen th at the vertical cut lift and several cut thereby forminga, heel of exceptional appearance.

eferrin' now to Fig. 1, at 10 is shown the machine. .On this table are located three standards 11, 12, and 13, which support the various working instrumentalie ties of the machine. Thecutting block is shown at li-fiind is circular in form'having anedge contour'corresponding with the ex terior of the heel to be trimmed so that an adequate support will be furnished the heel while it is beingtrimmed. It-is'mounted on a shaft 15-so that it is revoluble and can be moved from time to time the operator wearing too much in ,onefiplace.

The shaft 15 is mounted in a fork 16 bein adjustable vertically therein-by means o the set screws 17, 17. The fork i6 is mount-v ed on one end of the slide'l8 in the standard 11 and is adjustable longitudinally by means of the adjusting screw 19 and set screw 20. These parts hold the block firmly but per-- mit such adjustments as are necessaryfrcm time to time. At 21, is shown the horizontal knife which for convenience 1' have called the breast knife. his is mounted on one end of theslide 22 the ends er which pass through suitable guideways in the standards 12 and 13. The breast knife bar 22 is reeip-- rocated horizontally by the crank arm 23 pivoted at oneend to the collar 24: and at the other end 10 the crank pin 25 on the gear 26. The gear 26 meshes with the small gear 27 on the main shaft S28. The gears 26 and 27 have a two-to-cne ratio so that'the breast knife will make a completereciprocation for. each two revolutions of themain-shafi; 2h?

port. Fig. 7 is a bottom plan view of the stop mechanism of; the general typeshowr in my prioi" application. Itconsi'sts in a roll and cam clutch 29 and a cam 30 having a notch. 31 inits'facef I A632 -(see also Fig. l) is shown the start ing lever. This lever hangs from theunder side of the table and is fast to a rod'33'bn' hs t iie d of whi h s. a k darm 3% which siirrouhds the Vertical pin 35 "efi ag ing a suitable notch 36 therein. The endtof the pin'35 is in the path of rotation of the notched cam 3.0; :At spring;'.3-'Zitnds"to holdt the-forkedrann 34 andcpin35 in their upper most position; sorthat the end; (if 1 the pin 35' is in the path offthecam'except when phlled 1 down by the "movement? of the "starting'l'e er as; start. the machine.

It will-be seen that this mechanisyn provides simple and effective: means for causing the breast knife to' come t'o'i'est after'each complete reciprocation.
